Shading on toned paper (figure)

The video tutorial demonstrates how to use a white charcoal pencil and an extra soft graphite pencil to shade and highlight a drawing of a mannequin. The instructor first outlines the use of black to identify and fill in shadows, emphasizing the importance of squinting to see these areas clearly. After completing the shadows, the focus shifts to using white to highlight the lightest parts of the drawing, leaving some areas of the toned paper visible. The tutorial concludes with encouragement to apply these techniques in personal drawings.
